Failed to check out license 'ansoft_distrib_engine' Error code -2
The error message states that there is a license error due to requiring the HPC to distribute the parametric variation of a simulation. This normally requires a separate license called DSO. The parametric variation can still be done but in series and still using the HPC to distribute the frequency points as required. In the HPC and Analysis option please select the configuration needed and then press the Edit button followed by the "job Distribution" tab. In the last please uncheck the "optimetrics variations" and leave only the "frequencies" checked on.
